Garlic for Dogs: Home Remedies and Safety Issues

Hi, I have a boerboel, Jessie. She had a black growth on her ear that just got bigger and bigger, I started to smear ordourless garlic, which is 4 times stronger. Is now healed completely and nothing has grown back for 6 months now. Due to her age she developed a tumor on her back, I started again, on and off 3 capsule every 3 days, and its shrinking, still busy with her treatment. Did have to shave the area a bit,
